The above exploratory GEE analyses was tested in African American and biracial subjects (n = 58). Consistent with the results reported earlier, ancestral proportion scores (χ2 = 19.3, p < .001), TTES (χ2 = 9.3, p < .005), and the G×E interaction term (χ2 = 7.8, p < .006) were significant predictors of aggression.
